(C++26)
Member functions
Non-member functions
adjacent_view() requires std::default_initializable <V> = default;
(1)
(since C++23)
constexpr explicit adjacent_view( V base );
(2)
(since C++23)
Constructs an adjacent_view.
1) Default constructor. Value-initializes the underlying view.
[edit] Parameters
base
-
the underlying view
[edit] Example
Run this code
#include <iostream> #include <ranges> #include <string> #include <tuple> template<class... Ts> void print(std::tuple <Ts...> const& tuple) { std::apply ([&](auto&& arg, auto&&... args) { std::cout << arg; ((std::cout << args), ...); }, tuple); std::cout << '\n'; } int main() { const std::string v{"ABCDEF"}; constexpr int window_size{4}; std::cout << "v: " << v << '\n'; auto view = std::views::adjacent <window_size>(v); // overload (2) for (auto const& tuple : view) print(tuple); }
Output:
v: ABCDEF ABCD BCDE CDEF
